The answer is The Internet. It is a vast global network that is made up of many smaller interconnected networks. It connects to millions of computer units world wide, in which any computer can communicate with any other computer as long as they are both connected to the Internet. It also made access to information and communication easier.
Answer:
Program :
list_1=[]#take the empty list.
size=int(input("Enter the size of the list: "))#take the size of the list from the user
for x in range(size): #for loop which insert the elemnt on the list.
list_1.append(int(input("Enter the "+str(x+1)+" element of the list: ")))#take the user input and insert the element.
element=int(input("Enter the element to be searched: "))#it take the elemnt to search.
loc=1#intialize the location value.
count=0
for x in list_1:#for loop to check the element.
if(x==element): #check the element.
print(loc,end=", ")#print the location of the element.
count=count+1
loc=loc+1
if(count==0):
print("The element is not present on the list")#print when elemnt are not present.
Output:
- If the user input 5 for the size and 1,2,3,4,5 for the list and 5 for the element, then it will print 5.
Explanation:
- The above code is in python language which is used to take the size for the list, then take the value to add on the list.
- Then the element is entered from the user to search on the list.
- Then the element is searched on the list with the help of for loop.
- It prints the location when the element is matched.
Answer:
Following are the program in the C++ Programming Language.
//set header file
#include <iostream>
//set namespace
using namespace std;
//define class
class format
{
//set access modifier
public:
//set string type variable
string res;
//define function
void names(string first_name, string last_name)
{
//set if-else if condition to check following conditions
if(first_name.length()>0 && last_name.length()>0)
{
res="Name: "+last_name+", "+first_name;
}
else if(first_name.length()>0 and last_name.length()==0)
{
res="Name: "+first_name;
}
else if(first_name.length()==0 and last_name.length()==0)
{
res="";
}
}
//define function to print result
void out(){
cout<<res<<endl;
}
};
//define main method
int main() {
//set objects of the class
format ob,ob1,ob2;
//call functions through 1st object
ob.names("John","Morris");
ob.out();
//call functions through 2nd object
ob1.names("Jhon","");
ob1.out();
//call functions through 3rd object
ob2.names("", "");
ob2.out();
}
<u>Output</u>:
Name: Morris, John
Name: Jhon
Explanation:
<u>Following are the description of the program</u>:
- Define class "format" and inside the class we define two void data type function.
- Define void data type function "names()" and pass two string data type arguments in its parameter "first_name" and "last_name" then, set the if-else conditional statement to check that if the variable 'first_name' is greater than 0 and 'last_name' is also greater than 0 then, the string "Name" and the following variables added to the variable "res". Then, set else if to check that if the variable 'first_name' is greater than 0 and 'last_name' is equal to 0 then, the string "Name" and the following variable "first_name" added to the variable "res".
- Define void data type function "out()" to print the results of the variable "res".
- Finally, we define main method to pass values and call that functions.
Answer:
User Mode
Explanation:
Programs Can be Executed in two modes namely:
- <em>User Mode</em>
- <em>Kernel Mode</em>
User Mode
In User mode, the executing program has no ability to directly access hardware or reference memory. Program running in user mode must delegate to system APIs to access hardware or memory. Due to the protection afforded by this sort of isolation, crashes in user mode are always recoverable. Most of the program running on your computer will execute in user mode.
Kernel Mode
In Kernel mode, the executing program has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system. Crashes in kernel mode are catastrophic; they will halt the entire PC.
Answer:
SELECT inventory_id, film_id, title, store_id, address_id
FROM Inventory.Inventory
JOIN Business.store ON Inventory.store_id = store.store_id
JOIN Business.rental ON rental.film_id = Inventory.film_id
JOIN film_text ON Inventory.film_id = film_text.film_id
WHERE COUNT(rental_id) = 0;
Explanation:
The JOIN clause is also used to query tables from two databases. The Inventory and the Business database are joined in the inventory and store table respectively. The Query also joins the inventory table and the film_text table to get the title or name of the film rented where the rental_id count is equal to zero.
